1. A method of processing a broadcast signal in a transmitting system, the method comprising:
encoding, by a first Forward Error Correction (FEC) encoder, service data for a service that is carried by one or more Real-Time Object Delivery over Unidirectional Transport (ROUTE) sessions;
encoding, by a second FEC encoder, low level signaling information for fast channel scans and service acquisition of one or more services including the service, wherein the low level signaling information includes first service identification information for identifying the service, service category information for the service and capability information for the service;
encoding, by a Low Density Parity Check (LDPC) encoder, physical layer signaling information including information for identifying whether the low level signaling information is included in a current signal frame;
modulating, by a modulator, data of signal frames that include the encoded service data, the encoded low level signaling information and the encoded physical layer signaling information; and
transmitting, by a transmitter, the broadcast signal including the modulated data.
